Samsung Display has been teasing some of the screen technology that it's working on for future smartphones, as part of the Display Week 2021 virtual conference. We've got foldables, slideables, and an under-display camera.

We've already seen several foldable phones from Samsung of course, but the latest concept to see the light of day is a 7.2-inch OLED display with a double fold – it means bigger displays can be folded down into smaller units, and part of the original screen stays on show at all times.

Samsung is calling this an "S-foldable" screen, based on what we can gather from an auto-translation of the original Korean press release. Once Samsung has the production processes in place and enough confidence in the durability of the design, expect to see this appear on a future smartphone.

Then there's a 17-inch, 4:3 aspect ratio foldable screen that is tablet-sized when folding and the size of a computer monitor when unfolded – Samsung has attached the tagline "carrying small, seeing big" to this product, which allows two apps to be run side by side very easily (it looks like PowerPoint and Word in the example image).

This prototype reminds us of the Surface Neo concept that Microsoft showed off in 2019, though Samsung's version is bigger. It's going to need some kind of stand to hold it up when it's unfolded, it looks like, while input could be provided by the touchscreen itself or attached peripherals.

Samsung has given us a new glimpse of its rollable screen technology as well, a type of technology that multiple manufacturers are known to be working on. It enables a phone to stay compact for carrying but with the option to extend the display when extra screen space is needed.

A complex system of rollers and hinges is required to pull this off, but it is potentially a more durable and robust option than the standard foldable screen, while offering some of the same versatility in terms of display sizes.

Lastly there's also Samsung's UPC or Under Panel Camera, which here it's demoing in the form of a laptop webcam (it could also function as a smartphone selfie cam). The trick is getting the display layers above it to be transparent enough for the camera to see through.

Technology like this is already on the market, though at the moment it doesn't function particularly well. When the optics have been successfully refined, it will mean smaller bezels and no more need for the notch on phones and tablets.

All of these display innovations are still works in progress, and Samsung has yet to attach them to real products with actual release dates – but they offer up an intriguing look at what's coming down the line for the electronics of the future.

Next: unroll and then unfold in the other direction!

Folding screens are kind of a solution in search of a problem. I don't really see what they add that you couldn't get with a hinge and 2 flat screens. The "seam" is less noticeable on the folding screen at first until a few months of use. There is a lot of effort that goes into using scratch resistant glass on phones that will not fold and most people use screen protectors over top of that that will also not fold. By the time you have applied 2 different screen protectors to opposing sides of the area that's supposed to fold you have essentially completely defeated the purpose as there is now a gap and seam between the visible screen protectors anyway. Any surface that folds is too soft and prone to scratching for a mobile phone but the manufacturers don't really care because their goal is only for it to last just long enough for the next model to launch.

I want a blueprint sized roll able screen, that I can (digitally) draw on, that would be great on the job site. Flip pages with the small swipe of the finger, have tab on the top to switch between mechanical, electrical, architect, etc. Samsung, Make it so!
